Objective The aim of this study was to observe the outcome and evaluate the clinical efficacy of pulsed electromagnetic fields (PEMF) on pain management in patients with osteoporosis.MethodsA total of 58 patients with osteoporosis were treated with PEMF stimulation.Pains as main indicators of their symptom were evaluated before and after treatments.The clinical outcomes were assessed by observing the visual analogue scale (VAS).Statistical analysis was carried out to support the data.Results After PEMF treatment,the patients exhibited significant pain relief from mean VAS of 6.97±1.83 to 3.36±1.69(t-test,P＜0.05 ).Of the 58 patients,28 obtained significant symptom alleviation and 18 obtained moderate symptom alleviation,while 8 obtained slight alleviation,indicating the total clinical efficacy of 93%(54/58).Conclusion The current study provides the clinical outcomes indicating that PEMF may help to release the pain from primary osteoporosis and it might be an applicable supplementary treatment method for the osteoporosis related pain.

Objective To detect the expression of long non-coding RNA (lncRNA) CCAT1 in human papillary thyroid cancer, and to observe the effect of CCAT1 down-regulation on the invasion and migration of human papillary thyroid cancer.Methods The expression of CCAT1 was detected in human normal thyroid Nthy-ori 3-1 cells and human papillary thyroid cancer TPC-1 cells.CCAT1 siRNA plasmid was transfected into TPC-1 cells.The effect of CCAT1 down-regulation on cell invasion and migration was observed by Transwell chamber assay and scratch test, and the expressions of BRAF, MUC15 and RKIP proteins were detected by Western blot.Results The level of CCAT1 in human papillary thyroid cancer TPC-1 cells was significantly higher than that in human normal thyroid Nthy-ori 3-1 cells.CCAT1 down-regulation significantly inhibited the invasion and migration of TPC-1 cells.The Transwell invasion assay revealed that the number of migrated TPC-1 cells in the CCAT1 down-regulation group was significantly lower than that in the control group.The scratch test showed an increased distance between cells in the CCAT1 down-regulation group compared to the control group, suggesting a reduced cell motility.The expressions of BRAF and MUC15 proteins were decreased in the CCAT1 down-regulation group, while that of RKIP protein was increased.Conclusions The expression of CCAT1 in papillary thyroid cancer cells is significantly higher than that in normal human thyroid cells.Down-regulation of CCAT1 in papillary thyroid cancer cells may inhibit the cell invasion and migration by regulating the expression of BRAF, MUC15 and RKIP proteins.

Objective To study the clinical application value of humidified high flow nasal cannula(HHFNC) on bronchitis in children.Methods Total 85 cases of bronchitis that needed oxygen therapy in our department from Oct 2015 to Feb 2016 were randomly divided into three groups,HHFNC group,NCPAP group and nasal cannula oxygen group(control group).According to the blood gas results,FiO2 was adjusted to maintain PaO2 in 50~70mmHg(1mmHg=0.133kPa),TcSO2 90% to 95%.The main symptoms and signs(wheezing,shortness of breath,three depression sign,wheezing rale) disappeared time,length of oxygen inhalation and stay,the change of PaO2,PaCO2,respiratory rate were compared among the three groups.Results Compared with control group,the clinical symptoms and signs disappeared time and length of oxygen inhalation and stay were significantly shorter in HHFNC group(P<0.05).The recovery of blood gas and respiratory rate in HHFNC group were better than those in control group(P<0.05).No statistically significant differences existed between HHFNC group and NCPAP group(P>0.05).Conclusion HHFNC can significantly improve the clinical symptoms,signs and blood gas results in children with bronchitis,reduce the length of oxygen inhalation and stay.HHFNC is an effective and well-tolerated treatment for bronchitis in children.

The moisture content and the total ash ofXiang-Shan population were the lowest; and the extract content was the highest. The total ash ofLiu-De population was the highest; and the extract content was the lowest. The moisture content ofShun-Zhou population was the highest. It was concluded that different populations had different quality among 16 populations of wild herbs. Therefore, there was a probability to choose the best population.

Objective To analyze the relationship between fasting plasma glucose (FPG) level and complexity of coronary artery lesions in patients with coronary stenosis by angiography. Methods The data of clinic and coronary angiogram (CAG) were retrospectively collected in 929 patients with established coronary stenosis by coronary angiography at Peking University Third Hospital from January 2009 to January 2011. The patients were grouped according to SYNTAX score, and the relationship between FPG level and SYNTAX score were analyzed using bivariate, Multivariate stepwise regression and logistic regression analysis. Results ①929 patients were devided into three groups:47 cases into low risk group (score<22), 189 into moderate risk group (score≥22 and<33) and 639 into high risk group (score≥33). Intergroup analysis showed that age (P=0.000), FPG level [5.20 (4.70,6.30) mmol/L, 5.70 (4.90,7.15) mmol/L, 5.80 (5.30,7.60) mmol/L, P=0.000], proportions of FPG abnormality [283 (40.8%), 100(52.9%), 28(59.6%), P=0.001] and patients with diabetes history (P=0.003) were increased along with SYNTAX score elevated.②Correlation analysis showed correlativity (r=0.167, P=0.000) between SYNTAX score and FPG. In non-diabetes history subgroup, correlation between SYNTAX score and FPG remained signiifcant (r=0.149, P=0.000). However, in diabetes history subgroup, the correlation was not significant. ③ Multivariate stepwise regression analysis showed an independent correlation between FPG and SYNTAX score (β=0.452, P=0.002). In non-diabetes history subgroup, the correlation remained significant (β=1.039, P=0.000).④ When moderate-high risk group serve as dependent variable, and age, gender, CAD risk factors and FPG serve as independent variables, logistic regression analysis screened out two variables:age (whole group:OR 1.033, 95%CI 1.017 ~ 1.049, P=0.000;non-diabetes history subgroup:OR 1.039, 95%CI 1.020 ~ 1.059, P=0.000) and FPG (whole group: OR 1.114, 95% CI 1.038 ~ 1.195, P=0.003; non-diabetes history subgroup:OR 1.299, 95%CI 1.088 ~ 1.387, P=0.001). Conclusions FPG is likely to relfect complexity of coronary artery lesions and predict SYNTAX score in patients with coronary stenosis, especially in patients without diabetes history.

AIM: To study the effect of Jiunaoning Injection on apoptosis and the changes in cytosolic calcium induced by hypoxia/hypoglycemia in SH-SY5Y human neuroblastoma cells. METHODS: The apoptosis and the changes in cytosolic calcium were induced by hypoxia and hypoglycemia .Apoptosis was measured via flow cytometry(FCM), and cytosolic calcium was determined by Fluo-3 fluorometry. RESULTS: The hypoxia/hypoglycemia induced apoptosis and increased the cytosolic calcium in SH-SY5Y cells. Jiunaoning Injection inhibited the apoptosis of the SH-SY5Y cells and decreased the concentration of cytosolic free calcium. CONCLUSION: Hypoxia/hypoglycemia induced apoptosis and increase in cytosolic free calcium in SH-SY5Y cells, which were significantly inhibited by Jiunaoning Injection.

Objective:To construct a hypoglycemia nursing information system and explore its application effects in the nursing quality management of the Department of Endocrinology.Methods:Based on the existing blood glucose information management system of Peking University First Hospital, a hypoglycemic nursing information system with evaluation, alarm, record, remind, and management functions was designed. We compared the number of cases of standardized correction of hypoglycemia in inpatients by nurses, the complete and accurate cases of hypoglycemia records, and the monthly time spent on the quality control by nursing special managers before the application of the system (from February to December 2017) and after the application (from January 2018 to December 2019) .Results:After the application of the hypoglycemia nursing information system, the complete and accurate cases of hypoglycemia records, and the cases of standardized correction of hypoglycemia were statistically different from those before the application of the system ( P<0.001) . The quality control time of nursing special managers decreased from (7.55±1.01) hours a month to (0.41±0.21) hours a month. Conclusions:Application of the hypoglycemia nursing information system adapts to the hospital's management requirements for hypoglycemia, which not only promotes the standardization of nurses' handling of hypoglycemia events, improves the completeness and accuracy of written records, but also saves time for managers to perform the quality control and promotes the scientific and digitalization of nursing special management.

Objective To explore the value of serum stearoyl sphingosine(C18∶1-Cer)and 1-stearoyl-sn-glycero-3-phospho-choline(LPC 18∶0)levels in pregnant women's serum samples during pregnancy in predicting gestational diabetes mellitus(GDM).Methods The clinical data and laboratory indicators of 126 pregnant women were retrospectively analyzed.The sub-jects were divided into GDM group(n=66)and control group(n=60)according to the GDM diagnosis results.Mass spec-trometry was used to detect the serum C18∶1-Cer and LPC18∶0 levels of the subjects in early and mid pregnancy.Logistic re-gression analysis was used to screen out the risk factors for GDM.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of C18∶1-Cer,LPC18∶0 and their combination for GDM.Results Compared with the control group,the serum C18∶1-Cer and LPC18∶0 levels of the subjects in the GDM group were significantly increased in early(18.92±2.77ng/ml vs 23.47±4.18ng/ml,41.32±17.55ng/ml vs 88.08±16.02ng/ml)and mid pregnancy(23.14±4.10ng/ml vs 18.76±4.05ng/ml,84.60±14.53ng/ml vs 40.50±17.79ng/ml),and the differences were statistically significant(t=7.127,15.637;-5.984,2.174,all P＜0.05)C18∶1-Cer was positively correlated with fasting plasma glucose(FPG),fasting plasma insulin(FPI),homeostasis model assessment of insulin resistance(HOMA-IR),glycated hemoglobin(HbA1c)and triglyceride(TG)(r=0.458,0.209,0.317,0.223,0.219,all P<0.05).LPC18.0 was positively correlated with FPG,FPI,HOMA-IR,HbA1c,total cholesterol(TC)and TG(r= 0.715,0.426,0.580,0.465,0.232,0.372,all P<0.05).Logistic regression analysis results showed that C18∶1-Cer[OR(95%CI):1.522(1.136～2.039),P<0.05]and LPC18:0[OR(95%CI):1.198(1.102～1.302),P<0.001]were independent risk factors for GDM.ROC curve analysis results showed that the area under the curve(AUC)of serum C18∶1-Cer,LPC18∶0 and the combination of the two indicators were 0.819,0.971 and 0.986,respectively.The predictive performance of the combination of the two indicators was better than that of the single detection.Conclusion Serum C18∶1-Cer and LPC18∶0 in early pregnancy were closely related to the occurrence of GDM.C18∶1-Cer combined with LPC 18∶0 has a certain predictive value for the early diagnosis of GDM.

ObjectiveTo determine the optimal dose of Dachengqi Decoction （大承气汤， DCQD） for the treatment of acute intestinal obstruction （AIO） through a randomized， double-blind， dosage parallel controlled， multi-center clinical trial， and to providee evidence support for the reasonable dosage of DCQD in clinical practice. MethodsBased on the commonly used clinical dose of DCQD， three different groups were set up， including low-dose group which used Dahuang （Radix et Rhizoma Rhei） 12 g， Houpo （Cortex Magnoliae Officinalis） 9 g， Zhishi （Fructus Aurantii Immaturus） 9 g， and Mangxiao （Natrii Sulfas） 4.5 g， medium-dose group using Dahuang 36 g， Houpo 27 g， Zhishi 27 g， Mangxiao 13.5 g， and high-dose group using Dahuang 60 g， Houp0 45 g， Zhishi 45 g and Mangxiao 22.5 g. Initially， 149 AIO patients with Yangming （阳明） bowel excess syndrome were randomly assigned to three groups using a stratified randomization method， and both the patients and the doctors were blinded. In addition to conventional western medicine treatment， each group was given 12 bags of granules made from the raw herbs of DCQD at different doses， taken orally or injected through a gastric catheter once every 6 hours， 3 bags each time， for 3 consecutive days. After treatment， the indicators of the three groups of patients with primary AIO and non-primary AIO were evaluated respectively， and the full analysis set （FAS） and per-protocol set （PPS） were used for analysis. The primary outcomes were the time to recover voluntary bowel movements and voluntary flatulence. The secondary outcomes were the ideal rate of spontaneous defecation and the ideal rate of spontaneous flatus. The occurrence of adverse events during the study was recorded and analyzed using the safety analysis set （SS）. ResultsA total of 91 patients with primary AIO and 58 patients with non-primary AIO were included in the FAS and SS analysis， while 80 primary AIO patients and 56 non-primary AIO patients were included in the PPS analysis. Both FAS and PPS analysis showed significant differences in the time to recover voluntary bowel movements and voluntary flatulence among primary AIO patients in different dose groups of DCQD （P＜0.01）， and the high- and medium-dose groups assumed less time than the low-dose group （P＜0.05）. There was no statistically significant difference in the ideal rate of spontaneous defecation and spontaneous flatus among the three groups （P＞0.05）. And consistent results were seen in the non-primary AIO patients among the three groups. Five adverse events occurred in primary AIO patients （3 in the low-dose group， 1 in the medium-dose group， and 1 in the high-dose group）， mainly manifested as abdominal distension and abdominal pain， and there was no statistically significant difference in the incidence of adverse events （P＞0.05）. No adverse events occurred in patients with non-primary AIO. ConclusionDCQD， as an effective treatment for patients with AIO， is commonly used at a medium dose for patients with primary AIO and at a high dose for patients with non-primary AIO. The therapeutic advantage is mainly reflected in the shorter time to recover spontaneous defecation and spontaneous flatulence and the improvement of intestinal function.
